A proper story has three acts, but the story of The Foolkiller submarine is missing two of them. Today, we're looking at act 2: the brief window of time during which we know where this giant steel craft was. We're also examining the three initial theories that people at the time held about where the thing came from, and who built it. To do that, we're going from The North Pole to The Center of The Earth and even all the way to the deep jungle depths of Ottawa Illinois. Get a free trial of The Great Courses Plus and three months of unlimited access for just $30 dollars by going to https://www.thegreatcoursesplus.com/theconstant (https://www.thegreatcoursesplus.com/theconstant) Get 10% off your first month of online counseling by visiting: http://betterhelp.com/theconstant (http://betterhelp.com/theconstant) and entering discount code "theconstant".
